The average price of gas in Arizona remains unchanged again this week. Triple-A Arizona says the average price at the pump for unleaded is $3.15 a gallon. Spokesman Aldo Vazquez says “this is the lowest stock level since the post-Hurricane Harvey period in 2017.” He adds, “so the low supply level has contributed to the increase in gas prices which is a level that we haven’t seen since July.” In Flagstaff, gas prices were a cent lower this week to $3.42 a gallon. Some stations are selling gas for $3.25 and lower. In Prescott, the average price of gas stayed at $3.14 a gallon for the second straight week. Some stations are selling gas for $3.03 and lower.
